Concurrent Submit | zhenzhen-vidu-q3-short-play-lowprice

"Short play" (短剧) is a whole genre: the vertical, drama-style mini-episodes that dominate mobile video in China - one-to-two-minute micro-soaps with a hook every ten seconds. Vidu Q3 has a model purpose-built for generating these, and this node is it. It's script-driven rather than single-prompt-driven: you give it a script name, a style, and character/scene/prop assets, and it turns them into an 8–12 second vertical shot. If you're in the 短剧 pipeline - or just want to see how close an API model gets to "direct this episode" - this is the node.

Two structural things set it apart from the other Vidu nodes. First, it's a low-price channel node: it doesn't take a bare apikey. It takes an api_config connection from the pack's zhenzhen-seedance2-low-price-api-settings node (the domestic 贞贞的平价AI小屋 channel at api.seedance.nz), falling back to the SEEDANCE_API_KEY / SEEDANCE_BASE_URL environment variables. Second, the concurrent wrapper runs it in the video pool (ten workers) with the same collect-in-Concurrent Collect Videos pattern.

Inputs that matter

• model - vidu-q3-drama-short-play or vidu-q3-ad-short-play. Drama for narrative, ad for commercial spots.
• prompt - the scene/script direction.
• script_name - name your script; Vidu treats this as a project handle.
• style - free text ("realistic" by default), not a dropdown.
• asset_type - character, scene, or prop; plus asset_name_prefix and asset_description. This is how Vidu labels what you're registering.
• asset_image1–asset_image14 - up to fourteen reference images for your assets. For a drama, that's your cast plus the locations and props.
• duration - 8, 9, 10, 11, or 12 seconds. 1080p and 9:16 are locked defaults - vertical is the point.
• api_config, seed, skip_error.

Output: a COMFLY_VIDEO_FUTURE task.

How it works

The wrapper follows the standard ComflyConcurrent.py pattern - validate, push the original Comfly_vidu_q3_short_play_lowprice call onto the bounded video executor (ten workers), return the future. The collector waits on all tasks, restores slot order, and reports per-slot status; failure_mode: placeholder degrades failures to blank clips.

Setup

Install the pack once - ComfyUI Manager (search "Comfyui-zhenzhen"), or:

cd ComfyUI/custom_nodes
git clone https://github.com/T8mars/Comfyui-zhenzhen

For the key, use the low-price settings node connected to api_config, or set the SEEDANCE_API_KEY environment variable. The domestic channel (api.seedance.nz) prices at roughly 75–80% of the overseas service, which is the whole point of this node's existence.

Gotchas

The asset system is where beginners lose time: assets are registered from your images with the name/description you provide, and the model only reuses them well if the reference is clean and consistent - one character per image, matching look, no busy backgrounds. Long-form coherence is the genre's eternal problem: a 12-second clip with a hook can look great and still not match the next clip's character. And remember this node uses the low-price key, not the main Zhenzhen key - mixing them up is the classic "why is my key being rejected" moment. Timeouts: check the async task page before assuming failure.
